These changes were made to address GCC -Wsign-compare warnings.
In this case, the vendor ID in the management structure was unsigned
and the vendor parameters to various helper functions were signed.
This adds a backend for flashdev that simulates a flash device with
adjustable delays to simulate real flash devices and offers
configurable flash parameters. This also migrates the JFFS2
filesystem tests to the flashdev framework and eliminates the
purpose-built simulated flash in the testsuite in favor of a more
generic and widely usable solution.
Set BSP_INTERRUPT_VECTOR_COUNT to 1 to avoid type limits and array
bounds warnings.
Make sure all functions using the default interrupt controller
implementation return a status of RTEMS_UNSATISFIED.
Update #5298.
Close#5377.
GCC generates type limit warnings when comparison is always true or
always false due to the limited range of the data type, This was in a
termios structure. For most of the cases in RTEMS, this was when
a variable of an unsigned type was compared to be < or <= 0.
Return the actual out of bounds size per page instead of the ioctl
return status. JFFS2 will happily operate with an OOB size of 0 and
instead put cleanmarkers in the normal page space of the flash.
Add "(void) param;" annotation to address unused parameter warnings.
Found with GCC's warning -Wunused-parameter.
The ACPI change set includes two headers which define debug macros. When
not building for debug, the instantiated inline functions generate
unused parameter warnings from every file they are included in. The
warning was disabled around the macro instantiations.
The maximum size of JFFS2 is 4GB minus the block size of the flash.
Enforce this limitation when setting up a filesystem on a flashdev
region that is larger than the maximum.
This also resolves some off-nominal memory leaks.
This adds an API call allowing for unregistration to include destruction
of private data that is not managed by the flashdev framework. This also
updates the existing consumers of flashdev to use the new private data
destructor callback.
Previously this RTC was using the file system-based i2c interface in
/dev. Since the RTC is initialized pretty early on during system init,
we call open() before stdin/stdout/stderr have been opened. RTEMS
assumes that stdin == 0, stdout == 1, etc., and fails when that isn't
the case. In particular, when stdin != 0, RTEMS assumes that it wasn't
configured with a console driver and skips opening stdout/stderr,
leading to confusing issues with the standard I/O streams.
The ACPI source has multiple tables where a Name field is defined.
The name field is a character array with a length of 4. All of the
string initializers are four characters plus a NUL. The code is
careful to use strn*() functions and intentionally avoids assuming
there is space for the NUL. With lots of entries in the various
arrays, this was clearly a design decision to save space.
This was caught by GCC's -Wunterminated-string-initialization
warning. The solution used is to use the "nonstring" attribute
recommended by the GCC manual.
Closes#5329
For the application configuration option
CONFIGURE_RECORD_INTERRUPTS_ENABLED, define
bsp_interrupt_get_dispatch_table_slot() in the application configuration
to avoid issues with the object link order within the RTEMS libraries.
Enable this option in an associated test.
Close#5244.

GCC currently has issues with false positive warnings about array bounds
violations when the value used as the index is a pointer. This slightly
reworks the code to make it cleaner and to avoid this warning.
Avoid reading from the pl011 data register unnecessarily. There is no
need to preserve the contents of this register as it is not normal
memory. This unnecessary read causes console spam when running under the
Xen hypervisor when the read FIFO is empty since the read is not
expected.
Provide missing GCC atomics helpers as part of BSPs where GCC
does not know how to provide it since the CPU's ISA has no
atomic instructions. The implementation provided in
bsps/shared/atomics/__atomic_test_and_set.c should work
on any single core CPU.
The BSPs that need thie function tend to have older cores. This

This is an update of many lingering embedded brains GmbH licenses from
the RTEMS License to the 2-BSD license where possible depending on the
joint copyrights.
Updates #3053.
This adds generic JFFS2 interworking code that allows JFFS2 to be used
on top of any flashdev backend. It currently only supports NOR flashdev
backends.
Accesses to the L2C registers performed by the L2C driver are now
serialized with spin locks. This avoids concurrent access to the L2C
registers by multiple processors. Proposed by GRLIB-TN-0021.
Update #4925.
